When 2 triangle sides are known, the third side must be:
Greater than the Difference of the other 2 sides and
Less than the SUM of the other 2 sides
Difference = 5
Sum = 53
So, the sides that fit this requirement are 7 and 31.

The shape which describe the shape of the sandbox is "A quadrilateral, because angle c and angle x are acute."
<h3>
What is Quadrilateral?</h3>
A quadrilateral is a four-sided polygon, having four edges and four corners.
Here, Diagonal = 14 ft.
Length = 12 ft.
Width = 8 ft.
14² = 196, 12² = 144, 8² = 64
8² + 12² ≠ 14²
so it is not a rectangle.
Now, 14² < 12² + 8²
this condition does not occur in rectangle, so it will be a quadrilateral and here sum of square of two adjacent side is greater than the square of third side (Diagonal). So that is an acute angle.
From this situation we can conclude that:
Thus, the shape which describe the shape of the sandbox is "A quadrilateral, because angle c and angle x are acute."

Answer:
Number of student tickets = 325
Number of adult tickets = 404
Step-by-step explanation:
Let,
x be the number of student tickets
y be the number of adult tickets
According to given statement;
x+y=729 Eqn 1
3x+5y=2995 Eqn 2
Multiplying Eqn 1 by 3
3(x+y=729)
3x+3y=2187 Eqn 3
Subtracting Eqn 3 from Eqn 2
(3x+5y)-(3x+3y)=2995-2187
3x+5y-3x-3y=808
2y=808
Dividing both sides by 2

Putting y=404 in Eqn 1
x+404=729
x=729-404
x=325
Hence,
Number of student tickets = 325
Number of adult tickets = 404
Because X squared isn't the same as 2 multiplied by X(any variable) meaning the moment you change your variable the expressions wouldn't equivalent.
EX.) 2*420=840 and 420^2=176400
